CVE-2023-5586Public exploit

Process crash via zero-valued WAV metadata

Published Oct 15, 2023 · Updated Sep 16, 2024

Null pointer dereference in GPAC before 2.3.0-DEV allows local users to crash MP4Box by processing a crafted WAV file. The PCM reframer accepts a zero channel count or sample rate from the WAV fmt chunk, leaves its output PID unset, and passes that null PID to packet allocation. Reaching the flaw requires MP4Box to process attacker-supplied media for DASH output; the demonstrated consequence is a process crash.
